This exhibition examines the work of artists who make optical vibrations and abstract spatial illusions a dominant aspect of their work. These various optical investigations may express an artist's interest in the science of optical mechanics, mathematical structures, or they may function as visual analogies to music or to a past psychedelic experience. They may be part of an investigation into cosmological realms, or of a macro/microscopic visual duality. In some instances, the work is an extremely focused investigation of the formal aspects of color and linear relationships. All of the pieces share an interest in patterning, color relationships and an obsessive attention to detail and craft. They are not, however, merely ironic tributes to "Perceptual Abstraction." Rather, they can be seen as a viable continuation of that short-lived movement. This is partly due to technological advances that have occurred since the 1960s, in materials such as resins and polymers, but is more importantly a result of the increasing dominance of computer technology in our everyday lives and associated breakthroughs in scientific imagery.
